I have boy/girl twins and for their 7th birthday they couldn’t decide on what they wanted to do for a theme. So I chose for them lol. I made my daughter a Barbie Doll Birthday Cake Design and my son a chinook helicopter. They both came out great.
For the Barbie I took my large glass Pyrex measuring bowl and sprayed it with non-stick spray and baked my cake in that. When it came out I turned it upside down to make her dress. I had bought a cheaper Barbie at the store so I could take her legs off for the cake. Then I stuck her in the cake and decorated her.
